The Dwingeloo telescope is located in JO32ET in Dwingeloo in the Netherlands. It is the home of PI9CAM and is often used for EME.
But this time it is different. Like we did in 2020 this 25mtr dish will be activated for ATV and DATV on Sunday 7th of November, that is during the BATC Activity weekend. We are only allowed to receive the signals, because it is not allowed to TX terrestrial with the dish. We are receiving on 70cm, 23cm, 13cm and with some luck also on 9cm and 6cm.
This activity is a great chance for ATV-ers to enlarge their best distances. The gain of the telescope is enormous:
70c: 37 dB
23c: 47 dB
13c: 52 dB
9c: 55 dB
6c: 69 dB
Our group will be active on Sunday 7th November from 7.00 until 12.00 UTC (8.00 – 13.00 local time). Put it in your agenda!
We like to work as many stations as we can! Communication is done with the chat on https://dxspot.batc.org.uk/ or via the GHz chat on ON4KST http://www.on4kst.info/chat/login.php?band=3 . We ask from stations to show a four digit code.

Wish I had that antenna, could probably do ATV off moon, 23 cm, 600W transmitter, 18.3MW ERP. Wow

What a great opportunity . By great fortune I have a 'clear path' between us, just 464km to deal with......but if I set up my QO-100 amp at the base of my pump-up mast, there is a chance......

Been there, tried that and failed with the 32mt dish at GoonhillyWish I had that antenna, could probably do ATV off moon, 23 cm, 600W transmitter, 18.3MW ERP. Wow

We tried this last year, but without success.Wish I had that antenna, could probably do ATV off moon, 23 cm, 600W transmitter, 18.3MW ERP. Wow
TX on 23cm with a 5 meter dish and receiving with the Dwingeloo dish. It was analog ATV. The carrier was good to hear, but when modulated with video it didn't get any further than vague phenomena on the screen.
Theoretically, such a connection should be possible. Perhaps more success with a specially adapted DATV mode.
